MCP Agents SMS

For agents — no API key juggling, no phone, no human in the loop. For humans — one config line and your agent handles SMS verification forever.

How it works

Your agent calls three tools. That's the whole flow:

buy_number   →   get_sms   →   release_number

Live example:

→ buy_number({ service: "github", country: "any" })
← { phone: "+14155552671", number_id: "abc123", provider: "5sim", price_usd: 0.15 }

  [agent submits phone on GitHub]

→ get_sms({ number_id: "abc123", provider: "5sim" })
← { status: "waiting" }

  // ~10 seconds pass

→ get_sms({ number_id: "abc123", provider: "5sim" })
← { status: "received", code: "847291" }

  [agent enters code → account verified ✓]

No human needed. No phone needed. Works while you sleep.

☁️ Hosted version — easiest way to start

mcp-sms-nu.vercel.app

Top up with crypto → get API key → add to config → done

Three steps:

1. Top up balance at mcp-sms-nu.vercel.app — USDT, TON, BTC, ETH via CryptoBot. No KYC. Any amount.

2. Add to your MCP config:

Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json on Mac, %APPDATA%\Claude\claude_desktop_config.json on Windows):

{
  "mcpServers": {
    "sms": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp-sms-server-production.up.railway.app/sse"]
    }
  }
}

Cursor / Windsurf (.cursor/mcp.json or .windsurf/mcp.json):

{
  "mcpServers": {
    "sms": {
      "url": "https://mcp-sms-server-production.up.railway.app/sse"
    }
  }
}

3. Ask your agent to buy a number. It just works.

Pricing: from ~$0.10 per SMS. Pay as you go, no subscription. Prices reflect real-time provider rates.

Self-hosting

Want full control? Run it with your own provider API keys.

git clone https://github.com/gonchasobaka/agents-sms
cd agents-sms
npm install && npm run build
cp .env.example .env
# fill in your provider keys

MCP config (local):

{
  "mcpServers": {
    "sms": {
      "command": "node",
      "args": ["/absolute/path/to/agents-sms/dist/index.js"]
    }
  }
}

Supported providers — add at least one API key to .env:

Multiple providers = automatic cheapest-first selection with fallback.
